Yukon Gear High Performance Gear Set For GM 8.5in & 8.6in in a 4.88 Ratio

This Yukon Gear & Axle ring and pinion set features a 4.88 ratio, designed for GM 8.5-inch and 8.6-inch axles. The gear tooth surface finish is specifically designed to reduce friction and heat, which is important for handling high torque conditions and extended use. These sets are built using high-grade steel, ensuring a solid foundation for your drivetrain, and are designed to fit OEM specifications.

Choosing the right gear ratio can make a big difference, especially if you've added more horsepower or larger tires to your vehicle. A 4.88 ratio is often selected to bring your engine's RPMs back into an optimal range for better acceleration and towing performance after modifications. Yukon engineers use advanced design and testing processes to ensure each set meets exacting standards, making this a reliable choice for a wide range of GM trucks and SUVs from the 1980s through the 2010s, including models like the Chevrolet C1500, Cadillac Escalade, and Buick Rainier.

Yukon offers a 1-year warranty against manufacturing defects, and for added peace of mind, they also provide a lifetime Y.E.S. Plan protection option. This set is designed for axles without ABS provisions and requires a notched driveshaft.
